Payback  The payback period of a project is the number of years it takes before the cumulative forecasted cash flow equals the initial outlay.  The payback rule says only accept projects that “payback” in the desired time frame.  This method is very flawed, primarily because it ignores later year cash flows and the the present value of future cash flows.

Payback Example Examine the three projects and note the mistake we would make if we insisted on only taking projects with a payback period of 2 years or less.

Book Rate of Return Book Rate of Return - Average income divided by average book value over project life. Also called accounting rate of return. Managers rarely use this measurement to make decisions. The components reflect tax and accounting figures, not market values or cash flows.

Internal Rate of Return Example You can purchase a turbo powered machine tool gadget for $4,000. The investment will generate $2,000 and $4,000 in cash flows for two years, respectively. What is the IRR on this investment?

Internal Rate of Return Pitfall 1 - Lending or Borrowing?  With some cash flows (as noted below) the NPV of the project increases s the discount rate increases.  This is contrary to the normal relationship between NPV and discount rates.

14
Internal Rate of Return Pitfall 2 - Multiple Rates of Return  Certain cash flows can generate NPV=0 at two different discount rates.  The following cash flow generates NPV=0 at both (-50%) and 15.2%.

18
Internal Rate of Return Pitfall 4 - Term Structure Assumption  We assume that discount rates are stable during the term of the project.  This assumption implies that all funds are reinvested at the IRR.  This is a false assumption.

Internal Rate of Return Calculating the IRR can be a laborious task. Fortunately, financial calculators can perform this function easily. Note the previous example.

Profitability Index  When resources are limited, the profitability index (PI) provides a tool for selecting among various project combinations and alternatives  A set of limited resources and projects can yield various combinations.  The highest weighted average PI can indicate which projects to select.
